C.) The table below specifies which numbered
resistances on the circuit board correspond to the
optional low limit and the optional high limit. Solder
the appropriate resistors in these places.
D.) Assemble the unit and mark the appropriate places
on the label for the optional limits.
E.) It is recommended to turn the rotary switch to the
optional positions and measure the resistance from
the tip to the body of the plug with an ohmmeter to
verify the resistances.
NOTE: Two (three for position 10) resistor locations are
connected in series are provided in case resistors need
to be added to achieve the desired total resistance.
Solder a shorting wire across the resistor locations that
are not used.
MAINTENANCE
Wipe the plug periodically with alcohol.
